Slip torque
As in the table below, the clamping type MSXP-C has different slip torque according to the bore diameter. Take care during selection.Unit : N・m
| Part Number | Bore Diameter (mm) | |||||
|---|---|---|---|---|---|---|
| 6 | 8 | 10 | 12 | 14 | 15 | |
| MSXP-25C | 0.5 | 0.6 | 0.7 | |||
| MSXP-30C | 0.8 | 1.1 | 1.5 | |||
| MSXP-36C | 0.7 | 1.2 | 1.8 | 2.2 | ||
These are test values based on the conditions of shaft dimensional allowance: h7, hardness: 34-40 HRC, and screw tightening torque of the values described in MSXP-C dimension tables. They are not guaranteed values.
Slip torque changes with usage conditions. Carry out tests under conditions similar to actual conditions in advance.

- This is a resin spring coupling with single-piece construction.
- It can be used in an environment or cleanroom where heat resistance and chemical resistance are required, such as FPD manufacturing equipment.
- PEEK superior in physical and chemical properties is adopted. Outgas quantity is extremely low.
- A plate spring formed by a slit allows eccentricity, angular misalignment, and end-play to be accepted.
